Question

Photo above! Find the area of this triangle (It says the answer is 405 but all I get when I do it is 810) please help!

Answer 1

the formula for the area of a triangle is 1/2(base×height)
30×27=810
810×1/2=405

Answer 2

So, the area of a triangle is base x height, divided by 2.

When you calculated the area, you forgot to divide the answer by 2, which left you with 810.

27 x 30 = 810
Answer/2 is equal to the answer:
810/2 is 405.

Hope this helps!
